This fixes an issue where VM would run the async* generator after a
`yield` / `yield*` even though the subscription may be paused or
cancelled.
Furthermore this fixes an issue where `StackTrace.current` used
in async* generator crashes VM and/or produces truncated stack
trace.
This fixes the following existing tests that were failing before:
* co19/Language/Statements/Yield_and_Yield_Each/Yield_Each/execution_async_t08
* co19/Language/Statements/Yield_and_Yield_Each/Yield_Each/execution_async_t09
* co19/Language/Statements/Yield_and_Yield_Each/Yield_Each/execution_async_t10
* language/async_star/async_star_cancel_test
* language/async_star/pause_test
New in reland: Allow the generator to to cause cancelling it's own consumer.
This addresses the issue of original revert

The `toString` used the sign of `hours` to get a leading `-`
when the duration is negative. However, a negative duration of
less than one hour would therefore miss out on the sign,
because `-0` is not an integer.
Now handles sign explicitly.
Fixes#48841.
